MySensors Light

Integrates MySensors lights into Home Assistant. See the main component for configuration instructions.

The following actuator types are supported:

MySensors version 1.4

MySensors version 1.5 and higher

V_TYPES with a star (*) denotes required V_TYPES. Use either V_LIGHT or V_STATUS and either V_DIMMER or V_PERCENTAGE for an applicable actuator.

For more information, visit the serial api of MySensors.
